Will NetBoost 2000 speed up your connection?
You can speed up all modems including 14.4, 28.8, 33.6, 56K, isdn, dsl and
cable modems! NetBoost 2000 is a utility that
can improve the speed at which you browse, send and receive e-mail, and
download files from the Internet. NetBoost 2000
adjusts and modifies the various "hidden" configuration
parameters used by the Internet protocol (TCP/IP) under Windows 95 and 98.
By default, the Internet settings in both Windows 95 and 98 do not come
optimized for people accessing the Internet with a Dial-Up or Modem
connection, but instead come optimized for In-House Networks (LAN's). By
adjusting and optimizing these settings, NetBoost 2000
can improve the performance of all your Internet-related software.
How does NetBoost 2000 work?
By default, most modems and network connections in Windows are not
configured to transfer data at their maximum or their most efficient speed
(e.g 28800, 56KB). Though the actual maximum transfer speed of your
network connection cannot be changed except by upgrading your hardware, NetBoost
2000 can increase the performance of your existing modem or network
hardware by up to 200%! NetBoost 2000 does this
by optimizing Windows network and modem settings so that the overall
efficiency with which data is transferred by your hardware is improved.
The Result
Faster web browsing, faster downloads, faster e-mail, faster online
gaming, faster audio/video streaming, and faster chat.
System Requirements
Any computer running Windows 95/98/ME.
Our Customers Quotes
"I've used NetBoost 2000 to configure
my system as recommended with an RWIN of Multiple x8. It is screaming! I
love it. Thanks so much!"
- Eric J. Klein (Windows 98, Microsoft
Internet Explorer 5.0 User, USA)
I am new to the internet and decided to try NetBoost
2000, because my connection was about 3 Kb/sec with 56 bps modem...
now my modem screaming at 5 Kb/sec and sometimes even higher!!
- Caroline E. Petitjean (Windows 98,
Microsoft Internet Explorer 5.0 User, Netherlands)
The results are fantastic!!! It's just amazing how much faster the
connections are. Everyone should know about and have this amazing product.

MaxMTU
MTU is the Maximum Transmission Unit that IP is allowed to use for a
particular interface. In general, the bigger the packet, the more data is
transferred in the same number of packets, so the routers work better and
you experience higher throughput. If your MTU is set too big however, your
packets must be fragmented, or broken up, by a router along the path to
the server. This results in a drastic decrease in throughput because the
destination has to reassemble the packets that the routers took the
trouble to fragment along the way and this thread of the code in both
server and router is usually sub-optimal. Therefore, you want to set the
MTU for each individual interface as big as possible but not so big as to
cause fragmentation along your most common paths. In practice, this is not
as difficult as it sounds. While it is true that MTU can vary along every
path your data follows to its various destinations, in practice the
Internet has only two or three MTU settings and the proper MTU setting for
your network adapters is easily determined with some simple tests. Most of
the Internet is built on Ethernet and serial lines. Ethernet has a maximum
frame payload of 1500 bytes, so the biggest MTU that you can possibly use
on an Ethernet is 1500 bytes, no matter what the MTU size is anywhere else
on the Internet. Win9x uses a default value of 1500 for Ethernet adapters.
The high-speed serial lines that make up the backbone of the Internet have
MTUs that match or exceed the MTU of Ethernet. High-speed local-access
circuits like cable modems, DSL, frame relay, T-1, and T-3 circuits have
MTUs that match or surpass the Ethernet MTU. In these situations the
Microsoft default value of MTU=1500 bytes works best. Unfortunately, the
low speed serial lines that connect dial-up telephone lines and ISDN to
the Internet do not always use the Ethernet MTU size. Those access servers
that don't support Ethernet frame sizes use the minimum allowable MTU
setting of 576 bytes or an intermediate frame size of about 1000 bytes. If
your network gateway dial-up adapter is used to connect to the Internet
via dial-up analog modem or ISDN, you should test the MTU to see whether
you can use the 1500 byte default, the intermediate setting of 1000 bytes,
or the minimum 576 byte setting. Microsoft defaults to a MTU (MaxMTU) of
1500 on all interfaces for Win95 DUN 1.2 and earlier. DUN 1.3 and Win98
add a configuration parameter for MTU (IPMTU) to the Dial-Up Adapter with
a default of "AUTO" which sets MTU=576 for speeds of 128 kbps or
less and MTU=1500 for higher speeds. In addition to the AUTO setting, you
may select "Small" for MTU=576, "Medium" for MTU=1000,
and "Large" for MTU=1500 and override the AUTO setting.
RWIN (TCP Recieve Window)
The TCP Receive Window size is the amount of receive data (in bytes) that
can be buffered at one time on a connection. The sending host can send
only that amount of data before waiting for an acknowledgment and window
update from the receiving host. Matching the receive window to even
increments of the MSS increases the percentage of full-sized TCP segments
utilized during bulk data transmission. MSS is the MaxMTU - 40 bytes for
TCP and IP headers. The RWIN default is 8192 bytes rounded up to the
nearest MSS increment for the connection. If that isn't at least 4 times
the MSS, then it's adjusted to 4 * MSS, with a maximum size of 64K. With
the Windows 95 default MaxMTU of 1500, the default RWIN is rounded up to
8760 (1460 * 6). You can greatly improve performance by setting this to a
lower value such as 4 times your MSS (MTU-40). The idea is to bring it to
a value below 8192. Many people have better success with 6, 8 or even 10*
MSS. In some cases, however, manually setting RWIN may decrease
performance because it takes the control away from windows, and if the MTU
is negotiated to a different value, then the size of the RWIN is no longer
an whole integer multiple. For this to be effective you must make sure
your MTU is set where it will not be negotiated to a lower value
TTL (Time To Live)
TTL is a field in the IP header which indicates how long a packet should
be allowed to survive before it is discarded. TTL essentially determines
the maximum number of hops permitted. Windows 95 default is 32, but with
the Internet growing larger all the time, it is worth changing it to the
larger setting of 64.
Auto Discovery
Auto Detection is Enabled by Default. This option enables the system to
automatically determine the Maximum Transmission Unit (MTU) value and
detect routers which do not return appropriate ICMP messages under some
conditions. Enabling this setting causes TCP to attempt to discover the
Maximum Transmission Unit (MTU or largest packet size) over the path to a
remote host. By discovering the Path MTU and limiting TCP segments to this
size, TCP is supposed to be able to eliminate fragmentation at routers
along the path that connect networks with different MTUs. This requires
implementation of the corresponding server side algorithm, however, and
presupposes all of the servers on the entire Internet only running MSFT
server software with server-side optimization features accessible from
MSFT web-browser client software. However, it is not recommended to
disable this setting as it would then cause an MTU of 576 bytes to be used
for all connections that are not to machines on the local subnet.
Disabling this setting can cause severe performance degradation because
fragmentation may not be compensated for.
Black Hole Detection
Black Hole Detection is Disabled by default. Enabling this option forces
the system to try to detect black hole routers. Black hole routers are
routers that do not send back ICMP (Internet Control Message Protocol)
fragmentation-needed messages while automatically determining the optimal
MTU value. This increases the maximum number of retransmissions performed
for a given segment. Setting this parameter when it is not needed can
cause performance degradation. So it is not recommended that you enable
this option unless you understand the implications of doing so.
